PRACTICE DRUM.

APPLICATION FILED FEB.27,1919.

@hinweg To all whom t may conce/ra.'

Be it known that LIL-inni A. Bowen, ya

Y citizen of the United States of America, re-

siding at'Boston, inthe county of Suffolk and State of Massachusetts, have invented new vand useful Improvements in Practice- Drums, of which the following is alspecication.

This invention 4relates to music and particularly to drums, said invention having for its object the provision of a practice drum or a device which will give practically the same rebound to the drum sticks without' being unduly noisy, thus making it possible for a performer to practise without annoying the occupants of adjacent rooms or buildings. Y n

A further object of this invention is to produce an instrument in which the vibratory action of one member' is such as to enable the performer to practise the rolland other movements commonly practised in drumming, so that such a performer will gain the skill and experience necessary for him to transfer to a drum and perform in practically the same mannerras'hey did'in practice, and acquire satisfactory results.

Vith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing theinvention in detail, reference will be had to the v accompanying drawings forming part of this specificationV wherein like characters denote corresponding parts in the several views, and in which- Y Figure l illustrates a plan view of an instrument embodying the invention; j

Fig. 2 illustrates a View in elevation thereof; and f L Fig. 3 illustrates a sectionalview. In these drawings 5 denotes a base, preferably of rather dense or hard wood having apertures 6 therein for the reception of lacing ribbon 7, which lacing ribbon is uti-V lized for binding the parts of the device and holding them on the base, as will presentlyr appear.

Superimposed onA the base is a layer ofv resilient sound insulating material 7a, suchk as felt, the said insulating material constituting a support or cushion` for what might be termed a sounding board 8 which, in the impact drum heads.

i Specification of Iietters Patent. Patented July 13,719,2(L Uapplication filed February 27, 191e.V iseriai No. 279,575. f

' present embodiment ofthe invention consists of .arather thin plate which may be formedhof'gutta percha, whalebone, or a composition, such as papier mch, fiberboard, or any relatively stiff yet flexible or vibratory material which will be aected by the impact of the drum sticks similar. to the effect occasioned by said sticks when they sense by those acquainted with the art of drumming.

Superimposed onthe plate `8 is a layer of felt 9 forthe purpose of serving as a supplementaryvibratory member or mute when it is desired to reduce the sound produced by practising on the sounding board 8.

The plate 8 has apertures 10 alining with the apertures 6 of the base and the supplementary vibratory member 9 has apertures ll at one end which aline with apertures in the baseand plate so that the lacing ribbon 7 may be passed through the apertures for the purpose of holding all the parts in aS-V seinbled relation `to one another and the said lacing ribbon mayhave lits ends anchored to a stud or pin 12 rising from the base. The

lacing ribbon 7- passes on each side of the cushion andrprevents lateral displacement of the cushion and the relation of parts is indicated and well'shown on the drawing.

A binding 13 is applied to the base and extends over an end of the cushion, plate and pad to give a finished appearance, said binding being secured to the base by fastenings 14;, such as tacks or the like.

The cost of manufacture of this device is comparatively small and the instrument presents a `neat appearance and the lacing ribbon or that portion of it which extends under the base constitutes a support so that the base can be su )ported on articles of furniture `without liability of scratching or marring the same.

I claim- Y l. In a practice drum, a base, a cushion thereon, a vibratory member entirely supported by the cushion, a ,sound reducing member superimposed on said Vibratory member, and means for securing the parts in assembled relation to one another.

2. In a practice drum, a base, a cushion thereon, a vibratory member entirely supported by the cushion, said Vibratory mem bei' 'being convex in cross-section, a sound reducing member superimposed on the vi.- bratory member, and means for securing the parts in assembled relation to one another.

A device of the class described, comprising a base, a sounding-board spaced therefrom, and cushioning means between said base and sounding board, said cushioning means entirely supporting the sound ing-board.

4. A device of the class described, comprising a base, a sounding-board spaced `from said base, cushioning means between said base and sounding-board, said cushioning means entirely supporting the soundingboard, and means for securing the parts in assembled relation to one another.

5. In a practice drum, a base, a cushion thereon, a plate supported by said cushion, and means for securing the parts in assembled relation to one another.

G. In a practice drum, a base, a cushion thereon, a plate supported by the cushion, said plate being convexed in cross-section, and means for securing the parts in assembled relation to one another.

In testimony whereof I a'llix my signature in presence of two Witnesses.
